The contribution provides an overview of possible experiments with mobile phones in physics lessons. The focus of the article is therefore on the “mobile phone” as an experiment tool. Besides the use of mobile phones for documentation, experiments with mobile phones for analysing gravity acceleration and diffraction phenomena of infrared remote controls as well as experiments of the topic acoustics are discussed. This paper includes relevant examples of the project “N.E.T.–New Media Experimental Tools”, which is located within the framework of situated learning theory based on the assumption that the authenticity of the media used in experiments has a positive learning impact on physics instruction. This assumption means that the learning success of the learners with regard to experimentation in physics lessons is greater, if a physical phenomenon is explored with experimental tools used every day (special focus on new media tools), albeit possibly for different purposes. The focus of this aspect of research is on the development of physical experiments using authentic media of this kind and on the impact of these media on learning and motivation.
